Quick Summary

The Eaton AFU0333 50 SA S752 conveyor belt control switch is designed to reliably regulate conveyors in hazardous locations for demanding applications. Installing rugged interlocks in dusty, explosive environments can derail uptime and complicate maintenance; this unit mitigates that risk with a copper-free aluminum body and Corro-free epoxy coating. It carries NEC/CEC compliance, IP66 ingress protection, and hazardous-location ratings (Class II/ Division 1 and Division 2), providing safety assurance across installations. For OEMs and field technicians, the 3 hub entries, 15 lb without switch weight, and 25 lb total operating force simplify wiring, setup, and service while enabling scalable, compliant conveyor control.

FAQs

The AFU0333 50 SA S752 is designed for Class II/Division 1 and Division 2 environments with IP66 protection and three 1" hubs, making it compatible with standard conveyor wiring, existing protective enclosures, and typical field interlock schemes. Its 15 A, 600 V rating supports common control circuits, enabling straightforward integration into many current installations without extensive rewiring or enclosure changes.
Key features include a copper-free aluminum enclosure with Corro-free epoxy powder coat, IP66 ingress protection, and NEC/CEC compliance with hazardous-location ratings. These characteristics ensure resistance to dust, moisture, and corrosive conditions while meeting safety standards required for Class II/III, Division 1 and Division 2 facilities, reducing regulatory risk.
Yes. The AFU0333 50 SA S752 provides two normally open and two normally closed contacts, enabling flexible interlock and signaling schemes. This configuration supports stop/start control, fault indication, and sequencing across multi-point safety systems, simplifying wiring diagrams and allowing safer, more reliable belt-conveyor control in dynamic production lines.
The rugged aluminum construction, corrosion resistance, and durable epoxy coating extend service life in harsh environments, lowering maintenance frequency and replacement costs. The compact 6.59 lb weight and 25 lb operating-force design ease installation and adjustment, reducing commissioning time and improving overall equipment effectiveness (OEE) for conveyor systems.
Official resources include the Eaton AFU0333 specification sheet, installation instructions, and hazardous-location certifications available through Eaton’s documentation portal and UL/Canadian certification references. These assets provide wiring diagrams, mounting guidelines, and compliance data to ensure correct installation and ongoing safety adherence across your facility.
